<P>PROBLEM TO BE SOLVED: To provide an electromagnetically variable transmission used for transferring mechanical force, from one rotary shaft to another rotary shaft. <P>SOLUTION: The electromagnetically variable transmission includes an outer rotor 14 and an inner rotor 12. One of the rotors has a plurality of permanent magnets, configured in pairs and facing an air gap 30, disposed in between the outer rotor 14 and the inner rotor 12. The other rotor has a plurality of slots 32, disposed with a space from a magnetically permeable core, that have embedded windings. According to the rotation of the outer rotor portion 14 and of the inner rotor portion 12, a magnetic flux path is generated among the permanent magnet pairs, the air gap, the outer rotor portion 14 core and the inner rotor portion 12 core, electric power is induced in the windings, and the windings transmits power between the inner rotor portion 12 and the outer rotor portion 14. <P>COPYRIGHT: (C)2008,JPO&INPIT |
